Read the first 7 Avionics Systems Compliance flashcards as text

  1. Under 14 CFR 91.413, Mode C transponders used in controlled airspace must be inspected and tested within the preceding:

    Answer: 24 calendar months

    14 CFR 91.413 requires transponders to be tested and inspected within the preceding 24 calendar months.

  2. What does the term 'TSO deviation' mean in avionics certification?

    Answer: FAA authorization to manufacture equipment that does not meet all TSO requirements

    A TSO deviation is FAA authorization granted to a manufacturer to produce equipment that does not fully comply with all provisions of the applicable TSO.

  3. An aircraft's glass cockpit Primary Flight Display (PFD) loses its attitude indication in flight. According to 14 CFR Part 91 Minimum Equipment List (MEL) concepts, the ASI's concern would be:

    Answer: Whether the aircraft has approved MEL provisions and backup attitude instrumentation

    An inoperative PFD attitude display must be addressed through MEL provisions, which require adequate backup instrumentation for continued safe flight.

  4. When an avionics modification requires changes to aircraft electrical load, what analysis must be performed?

    Answer: An electrical load analysis to verify the aircraft's electrical system capacity

    Any avionics modification that adds electrical load must be supported by an electrical load analysis confirming the aircraft's generator and battery capacity is not exceeded.

  5. TCAS II Resolution Advisories (RAs) are required to be inhibited below what altitude AGL during approach to landing?

    Answer: 500 feet AGL

    TCAS II is designed to inhibit Resolution Advisories below approximately 500 feet AGL during approach to prevent nuisance advisories near the ground.

  6. Which document would an ASI reference to determine if an avionics antenna installation meets structural and aerodynamic requirements?

    Answer: FAA Advisory Circular AC 43.13-2B

    AC 43.13-2B (Acceptable Methods, Techniques, and Practices — Aircraft Alterations) provides guidance on antenna installations including structural and aerodynamic requirements.

  7. A Part 135 operator is using a GPS navigation system for IFR operations that is approved under TSO-C129 but not WAAS-capable. Which approach type is this system NOT authorized to fly?

    Answer: LPV (Localizer Performance with Vertical guidance) approaches

    LPV approaches require WAAS capability (TSO-C146 or TSO-C196) and cannot be flown with TSO-C129 non-WAAS GPS equipment.
